Light Curtains and Safety Scanners
Light Curtains
Dangerous areas of a machine or production line that require regular operator access often utilise light curtains to protect agains unauthorised entry. Light curtains are available in many sizes, up to 2000mm long and are available in various resolutions.
Curtains with a high beam resolution are required for finger and hand detection, while curtains with low resolution are required for arm and body detection. Understanding the safety requirement is critical in selecting the correct length and resolution. Failure to do this can lead to excessive hardware costs or failure to adequately guard.
Safety Scanners
Safety Scanners continuously monitor a user defined (software configured) 2 dimesional zone. The scanner allows for complex areas to be included in the safety zone. PFI have designed safety scanners into applications that have offered challenging design constarints.
